Nanna is from the Old Norse nanna (woman, mother). **Nanna** was the Norse goddess and **wife of the beautiful god Baldr** — when Baldr was killed by Loki's trick and laid on the funeral pyre, **Nanna died of grief and was burned alongside him**. **The original "died of a broken heart."**
Featured in the Prose Edda.
Nanna reduces to four — the number of Norse devotion.
